Handling

  

CAUTION

Since the spring type contact tip is very thin and sharp, great care 

should be taken to prevent personal injury when the contact tip is 

mounted. In particular, handle the spring type contact tip with great 

care. The probe cable is a delicate part of the probe.  If the probe 

cable is bent or pulled forcibly, this may cause the cable to break.  

To keep the accuracy and protect the product, do not apply any 

impact or shock to the product.

Maintenance

Cleaning

When cleaning the exterior of the probe, clean it using a soft cloth rag moistened 

with either water or isopropyl alcohol.  In this case, dry the probe completely 

before starting the measurement.

Changing the Probe Tip

To change the probe tip, grip the tip firmly with pliers and carefully pull it straight 

out of its contact socket along the axis of the probe.

Adjustment Procedures

LF Compensation

Connect the probe to the CAL-output on the oscilloscope and adjust the “kHz” 

trimmer (see also the Figs. next page.) so that the observation waveform 

becomes the optimum square waveform.

 

Under Compensated 

Correct Waveform

Overcompensated
